UNITED TATES PATENT EErcEa HENRY PATTISON, OF ST. JOHN, NEW BRUNSWICK, CANADA.

COMBINED PRESS AND SAIVIING-IVICl-HNE.

SPECIFICATION forming part of Letters Patent No. 359,280, dated March 15, 1887.

Application tiled August 21, 1886. Serial No. 211,479.

To @ZZ wtom it may concern.-

Be it known that I, HENRY PATTIsoN, a subject of the Queenof Great Britain, residing at St. John, in the county of St. John, Province of New BrunsWick,Dominion of Canada, have invented a certain new and useful Improvementin Combined Presses and Double- Seaming Machines, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the artor science towhich said invention appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a perspective view of my improved press and double-steaming machine represented as mounted on the bench in position for use; Fig. 2, a side elevation of the same detached from the bench; Fig. 3, a vertical transverse section of the horizontal disk or bed-die, a portion of its supporting-shaft and the spring being shown in side elevation; Fig. 4, a vertical longitudinal section of the formers or rotary dies, a portion ofthe shaft on which they are mounted being shown in side elevation; Fig. 5, a diagram showing the position of the dies when the machine is used as a press; and Fig. 6, a like view, showing the position of the dies when the machine is used as a double-seamer.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

My present invention relates to that class of machines which are employed by tinners in the manufacture of tinware, being designed as an improvement on the device secured to me by Letters Patent of the United States, numbered 338,867, and bearing date March 30, A. D. 1886; and it consists in certain novel details of construction, as hereinafter fully set forth and claimed, by which the machine shown and described in said Letters Patent is not only rendered more effective in its operations, but adapted to serve the twofold purpose of a cover-press and double-seamen The nature and operation of the improvement will be readily understood by all con- Vversant with such matters from the following explanation.

In thevdrawings, A represents the body or bed of the machine, which is adapted tol be (No model.)

fastened to the bench B by the screws x. Mounted on one'end of the bed A there is a vertically-arranged standard, C, which is secured thereto by the nut and bolt m, said bolt passing through a slot (shown by dotted lines in Fig. 2) which extends longitudinally of the bed beneath the foot of the standard, thereby rendering the same adjustable.

Any other suitable means may, however, be employed for securing and rendering the standard adjustable, if desired.

Journaled horizontally in the upper portion of the standard C there is a crank-shaft, D, mounted in suitable boxes, f b, and provided with a spring, o, adapted to elevate the inner end of said shaft when pressure on the same is removed. A vertically-arranged standard, E, is also mounted on the bed A, being secured thereto by the nut and bolt x', said standard being rendered adjustable by said nut and bolt and the slot d in the bed, through which the bolt passes. A vertically-arranged shaft, H, has its lower end pivoted in a step, N, on the foot of the standard E, said shaft passing through an elongated slot (not shown) inthe arm O at the upper end of said standard. A horizontally-arranged disk or bed-die, K, is mounted on the shaft' H, said disk being dislishaped, or ,having a cavity on its upper side, and provided therein with a series of rabbets or shoulders, It, corresponding nearly in contour,

fixed on the shaft D, being adapted to work in connection with the die K, said formers being secured by the nut l?, and prevented from turning on the shaft by an ordinary spline, 12.

A lever, J, provided with a cam or projection, i, has one of its ends jointed to the top ofthe standard C and its other to a rod, L, which passes downwardly through the bench B and is connected with the treadle M, the projection t' being` adapted to engage the box f and force the dies t Z g z down onto the disk K when said treadle is depressed, the spring v raising said box and dies when said treadle is released. Instead of using the lever J, rod L, and treadle M for forcing the upper dies down onto the disk K, a screw or any other suitable means may be employed, if desired.

Attached to the standard C there is abracket, 7c, and mounted on a hovrizontallyarranged Stubshaft, a, which is rendered vertically adjustable in said bracket by the screw 13, there is a small wheel or roller, w, disposed beneath the edge of the disk K, and slightly in front of the die t', the object of said roller being to support the side or edge of said disk and prevent it from being broken by the pressure of the rotary dies or formers t Z g .5. This bracket and its roller may, however, be dispensed With, if desired.

The diet is provided peripherally with a double-seaming edge or rabbet, 14, adapted to Work in conjunction with the disk K when the machine is used as a double-seamer, as shown in Fig. 6, and With an annular iiange, 15, adapted to fit the annular groove 16 in the disk K, When the machine is used as a press, as shown in Fig.

The edges 17 of the disk K may be formed at right angies to the plane of its top for double-seaming pans and other vessels having straight sides, as shown in Figs. 2 and 3, orit may be inclined for double-seaming vessels having flaring or inclined sides, as shown in Figs. 5 and 6, it being understood, of course, that the shoulder 14 is to be formed accordingly.

A vertical socket, 1S, is formed in the upper end of the shaft H, and disposed in said socket there is a coiled spring, Q, which projects upwardly above the top of the disk K, and is provided with a cap, 20, preferably composed of leather, rubber, or similar material.

The object of the spring Q is to elevate the pan or vessel being` double-seamed and keep it out of Contact with the disk K, except at a point immediately under the bearing-surface of the die t, thereby preventing the bottom of the vessel from being scratched or defaced by the disk, in the usual manner.

Vhen the machine is used as a press, the spring acts fo elevate the edge of the cover,or piece eut from the cover, and enable thework man to readily remove it Afrom the disk.

In the use of my improvement as a press for the manufacture of tin or sheet-metal covers for pots, pails, de, the treadle M being elevated and the dies arranged as shown in Fig. 2, the circular blank from which the cover is to be made is placed on the disk or bed-die K. The treadle is then depressed and the shaftD turned, causing the dies on said shaft to press on the blank and force itinto the disk or bed-die, thereby forming the cover, in a manner which will be readily obvious without a more explicit description.

In the use of the improvement for doubleseaming, the standards are adjusted to bring the rabbet or double-scaming edge 1i of the die t into proper position with respect to the edge 17 of the disk K, as shown in Fig. 6, the article to be doubleseamed being then placed on the disk and double-seamed in the usual manner.

. A ring orbinder of tin provided with a down- Wardly-projecting annular fiange may be cmploycd to secure the blank on the disk K, if desired, when the machine is used as a press. The edges of the shoulders or rabbets h in the face of the disk K are angular; but theworking edges or periphcries of the dies t Zgon the shaft D are slightly rounded, so that saidlastnamed dies do not press the sheet-metal blank into the bed-die to make it conform precisely with said rabbets, but bend it in curves over them, thereby preventing the sheet from cracking or breaking under the pressure to which it is subjected and making a more desirable cover. By not bringing all parts of the sheet into contact with the bed-dic the cover is also prevented from being so badly scarred or scratched as it would be if pressed fully into the rabbets or angles 71..

It will be obvious thatone or more dies may be employed on the shaft D, and that the beddie K, and also the dies or formers on said shaft, are designed to be changed to correspond with the work to be performed or the style of cover to be made.

I do not confine myself to the use ofthe spring Q in the shaft H, as, when the machine is used for double-scanning, a stud projecting slightly above the top of the disk K may beinserted in the socket 18 and used instead of the spring; or the shaft H may be elongated to eX- tend above the top of the disk, if desired.

Having thus explained my invention, what I claim is- 1. In a machine of the character described, the combination of a vertically-arranged shaft, a horizontally-arranged disk mounted on said shaft, a horizontally-arranged shaft, a vertically-arranged die mounted on said horizontal shaft and adapted to engage said disk, a crank or means for rotating the die, a treadle mechanism or means for causing the die to press on the disk, and a spring or means for keeping the pan or other vessel elevated from the disk while being double-seamcd, substantially as described.

2. In a machine of the character described, the combination of the die f, provided with the double-seaming edgeor shoulder 14, the shafts D H, and disk K, said disk being recessed 011 its upper side for receiving a die or dies on the shaft D, and provided with the doubleseaming edge 17, substantially as set forth.

3. In a machine of the character described, the die provided with the shoulder 14 and annularflange 15, in combination with the disk K, provided with the annular groove or rabbet 16 and double-scaming edge 17, subst-antially as described.

4. In a machine of the character described, the spring Q, in combination with the shaft H, disk K, shaft D, and a die adapted to operate in conjunction with said disk, substantially as set forth.

5. In a machine of the character described, the combination of the shaft D, carrying a vcrtical die or dies, and the shaft H, mounted in IOO IIO

the standard E and carrying the disk K, said disk being provided with a double-seaming edge, 17, and reeessed on its upper side to reeeive'a die er dies on the shaft D, the stand- 5 ard being adjustable to enable the disk to be moved laterally into position for use with the die or dies on the shaft D, and thereby convert the machine froinapressnto adoublesearner, and vice Versa, substantially as described.
